Abstract Submission: Drinking water storage reservoirs regularly have the challenge of maintaining a sufficiently large supply for emergencies while also maintaining water quality and water age in the tanks. This presentation will summarize several evaluations that looked at the inlet and outlet configurations of storage reservoirs and identified zones with poor performance. Different tank modifications to inlets, outlets, and baffles were used to achieve each project specific goal. As tank mixing and detention time can compete with each other, the evaluations looked at striking the right balance to avoid short circuiting and high water age. The water entering these storage tanks have already been chlorinated so the ultimate goal was to avoid dead zones with high water age and low chlorine residuals.
Learning Objectives/Expected Outcome (Optional) : The learning objective is to show how CFD modeling was used to improve water quality and water age in a drinking water storage tank through innovative design solutions that were validated using CFD.
